Abstrakt
The paper describes a study realized with Slovak and Czech teachers of mathematics and physics. The pandemic and the sudden appearance of new types of resources, which appears in the preliminary results of the pilot study of the Horizon 2020 MaTeK project (in which are authors of this paper involved) implied the need to explore if teachers' behavior in resource use was changed due to Covid-19 pandemic in a long-term or only during the time of lockdown and shortly afterward.
Therefore, a questionnaire study focused on different use of resources with two lines of interest: differences between countries and differences between mathematics and physics teachers. The result of this study provides some crucial information about how teachers dealt with lockdowns and what the critical points and gaps in resource use are.
Some of these factors can be starting points for further research or can provide helpful information for authors of curricular resources.
